The Johnsons have a second home that was available to rent for four full weeks (28 days) during the summer. Of the twenty-eight days, the Johnsons rented it to unrelated tenants for 16 days at fair market value. In addition, the Johnsons rented the home to the Florians for four days. Because they are family friends, the Florians only paid half the market rate for the rent. The Johnsons also rented the home for five days to the Smiths.
